Because the amount of data stored on my drives is continuously increasing, I've decided that it's time to find a way to backup the most important part of it.
So, I'm looking for a software capable of making a backup copy(on a secondary HDD) of certain folders and of certain files(from certain folders) and keeping it updated.
I'm also interested to make a backup copy of files that are locked, if possible.
I have some VMs and I'd like to back them up too if possbile.(I'll check to see whether VMWare Workstation can backup itself by taking snapshots on a different HDD at certain moments).
The software really needs to be able to cope with paths longer than 255 characters, it has to be able to retain all the file's attributes(creation date, modified date, attribute fields, etc), and it has to ba able to do bit-by-bit checking in order to prevent corruption.
Also, there are some large files that I can't backup(it would take too much space), and in this case I'd like to have a list of their names and sizes, and if possible a checksum(TTH or emule's MD5), in order to redownload them easily in case of a disaster.
What software would you advise me to use?
BTW, I'm also very interested about your backup methods for your sensible data.
PS: Neither RAID nor a ZFS NAS box are solutions for me at the moment, and I'm not looking for a software that does backup to an entire partition.
